Operational Synthesis

status: complete
scope: scheduled higher-level operational synthesis

Summary

Material change is present: the user returned on 2026-09-02 after interview-related absence, attended/was preparing for NCN festival, and successfully requested and verified a published running-order timeline. The current architectural priority is a durable, session-independent polling/control plane before the future native prompt-builder backend, with a transitional ACP-resume adapter. A read-only architecture subagent was attempted but failed by timing out after malformed empty-input tool calls; it produced no verified design result.

Runtime and memory

memory-heartbeat.json (2026-09-03T04:07:47Z): restore ok=true, 7,504 entries, 6,463 visible and 1,041 filtered; semantic_changed=true; no archive.
model-heartbeat.json (2026-09-03T04:00:40Z): rc=0, acpx_rc=0, successful NO_CHANGE; no curated or reflection change.
context-guard.json (2026-09-03T04:07:25Z): direct ACP healthy at 177,328 provider tokens (16.9%), normal stage, no compaction/reload recommendation. Effective ceiling remains unobserved and based on the advertised GPT-5.6 Terra context.
Preferred model log is current through the NCN conversation, ending at 2026-09-02T18:04:39Z. It records the failed architecture-review job and the user's correction request for transparent explanation.

Durable user/current-topic state

NCN Festival (3–6 Sep 2026, Kulturpark Deutzen) is the active near-term topic. The published page https://pages.nvdll.org/ncn-2026-running-order.html was checked against the official running order; blank Saturday 15:20 Kulturbühne slot intentionally remains blank.
User wants a Claude-Code-like polling loop with arbitrary reasonable timestamps/intervals, retries/backoff, deadlines, dedupe/debounce, wake budgets, durable restart recovery, and visible subagent lifecycle/status.
Agreed architecture: isolated poller/watch state and event queue before the native backend; shadow mode first; current transitional path is poller → durable queue → ACP-resume adapter → current session; target is poller → queue → prompt builder → fresh backend turn. Do not evolve the fragile timer dispatcher in place or replace the live backend during the first phase.

Findings and hypotheses

Verified: Main direct ACP and memory workers are healthy; no current context pressure or restore failure.
Verified: The latest user-facing work completed successfully (page publication and schedule verification), so the prior model-log quiet period was not a sync backlog. Do not compare canonical/model line counts as missing messages.
Verified limitation: /home/matrix-lite/state/observability.jsonl is absent. Reads of /home/matrix-lite/state/turns.jsonl and /home/matrix-lite/workspace/state/timers/timers.json were denied by policy in this worker. Native Matrix-lite status tools were not available in the exposed tool set. Independent control-plane/backlog/timer/subagent verification is therefore incomplete.
Open operational risk: Generated continuity-summary.txt still says kimi-for-coding/k2p6, contradicting live openai/gpt-5.6-terra; fix the source/configuration or generator, never the generated snapshot directly. The existing high-priority action from 2026-08-17 remains open.
Open robustness risk: directed/index.json has historically re-inflated stale notices, and the curator previously experienced a zero-byte curated-memory.md truncation. These remain source/persistence hardening items, not reasons to alter the live backend now.

Actions for main agent/infrastructure

Continue the existing high-priority action to design/stage the isolated polling control plane. First inspect actual timer/direct-ACP seams and subagent state schema, then implement only shadow-mode state/queue and restart/idempotency tests. Keep the ACP-resume adapter narrow and replaceable.
Repair scheduled-worker model/config selection away from obsolete kimi-for-coding/k2p6; prove two clean scheduled runs and verify regenerated continuity output.
Obtain an independent control-plane smoke check when status tools/permissions are available: backlog missing_runtime_entries/needs_sync, timers, subagents, approvals, and observability.
Treat the old ImmoScout inbox follow-up and local YouTube archive as dormant, confirmation-gated tasks; do not initiate external actions from this worker.

Curated-memory proposals

None. The NCN festival/page activity and polling-loop design are useful warm operational context, but no new durable personal fact requires promotion to curated-memory.md in this scheduled cycle.

Files updated

This report (checkpoint replaced with completed synthesis).
/home/matrix-lite/state/persistent-chat/recent-topics.md (current topic/runtime entry added).

Subagents and blockers

No native subagent was spawned by this scheduled worker. The previously recorded job 9cec5ce3080c failed after malformed empty-input tool calls and a 900-second timeout; no architecture conclusions should be inferred from it.
No approvals requested. Missing/denied status surfaces are recorded above; they are non-fatal for this report.
